This is a media type registration as defined in Multipurpose Internet
Mail Extensions (MIME) Part Four: Registration Procedures [MIME-REG]
and Media Type Specifications and Registration Procedures

XML Encryption Syntax and Processing [XML-Encryption] specifies a
process for encrypting data and representing the result in XML. The
data may be arbitrary data (including an XML document), an XML
element, or XML element content. The result of encrypting data is an
XML Encryption element which contains or references the cipher data.

The application/xenc+xml media type allows XML Encryption applications
to identify encrypted documents. Additionally it allows applications
cognizant of this media-type (even if they are not XML Encryption
implementations) to note that the media type of the decrypted
(original) object might be a type other than XML.


Type name:

Subtype name:


Required parameters: 

Optional parameters: 

    charset, as defined in section 3.1 of RFC 3023 [XML-MT].

Encoding considerations:

    The encoding considerations are identical to those given 
    for 'application/xml' in section 3.2 of RFC 3023 [XML-MT].

Security considerations:
     See section 6 of the [XML-Encryption].

Interoperability considerations: 


Published specification: 


Applications which use this media type:

     XML Encryption is device-, platform-, and vendor-neutral 
     and is supported by a range of Web applications.
     See also section 4 of [XML-Encryption].

Additional information:

     Magic number(s): none

     Although no byte sequences can be counted on to consistently
     identify XML Encryption documents, they will be XML documents in
     which the root element's QName's LocalPart is 'EncryptedData' or
     'EncryptedKey' with an associated namespace name of
     'http://www.w3.org/2001/04/xmlenc#'.  The application/xenc+xml
     type name MUST only be used for data objects in which the root
     element is from the XML Encryption namespace. XML documents which
     contain these element types in places other than the root element
     can be described using facilities such as [XML-schema].

     File extension(s): .xml

     Macintosh file type code(s): "TEXT"

     list for the XMLENC Recommendation)

Intended usage:


Restrictions on usage:


     The XML Encryption Recommendation is a work product of the World Wide
     Web Consortium (W3C) and was edited by:

       Donald Eastlake <dee3@torque.pothole.com>
       Joseph Reagle <reagle@w3.org> 

Change controller:

     The World Wide Web Consortium (W3C) has change control over the 
     XML Encryption Recommendation and its related media types.
